'The coil of the heatingv element is made olf' 0 hare Wire of high resistance which becomesr very hot and I therefore provide guard l Wires 14, which cross and have their ends secured in apertures in the rim vof the re-I Hector., These guard Wires serve not only to 15 prevent any inconvenience by accidental hut also to pre-4r contact with the hot Wires, tect the heater unit from injury.

One form of my electric radiator is rshown in Figs. l and 2, in which it may be susconductor cord and attached by means of the ordinary plug to any lamp socket. It is necessary, however, Vto relieve the cord terminals i', 7', of any Weight or strain and furthermore to pre- For the purpose of providing a rm'substantial support which may be directly con-` y the metal dome and 3o lalso permit of attachinent'to the cord With-v out injury thereto, l employ a helical .L 'le' nected to the back of coil lo, preferably of spring metal. many turns of the 'helical wire constitute va radiator having a `large radiating surface 3.5 :suliicient to dissipate kthe majority of the dome loe-v fore it reaches the attachment to the cord.

heat conducted from the reflector The inner turn of the spiral 16a, is secured under a nut 18, which is fastened to the nach 40 `,of the dome by a screw 19, thus forming a` rigid connection between the helical spring and the dome'.

ln Figs. 5 and 6, l have shown a multiplel unit radiator having a plurality of heaters,l ribed, mounted upon the cross-arm of a standard 20,

In Figs. 7, 8 and 9, I have illustrated a modification oit' my invention in which the heater unit is mounted upon a tubular stem 5o or support 22, having a plug attachment 24,

upon one end, the reflectorlb being preferably semi-cylindrical. lilith'this forni it is Very convenient to insert a heater in any vlamp socket and they may also he substi- '55 tuted for the bulbs or glovvers inielectric heaters of the luminous radiator type.

While the forni of my radiator shown in Figs. l and 2, Serves admirably for most purposes, I have-found that it is often dcsirable to provide a radiator havingV an outer surface which lis less highly heated and which will not afford discomfort if the hand or face should come in contact with itz* fl have therefore devised the d uplex dome type sliownin Fig. l0,inivhich the main heat reof the cord by incassi,

iiector dome l is supported Within an outer dome l and spaced therefrom by distance pieces 30, into the ends of the fastening bolts which may be threaded. The outer dome may he of iolished metal and is preferably perforatcd, although this isnot absolutely essential. There is thus formed a channel or chamber between the inner and outer domes through which air may circulate and which will prevent the outer dome;` .rom becoming highly heated. i r

For the purpose of keeping the outer dome comparatively cool, l prefer to pcrforate it with holes, as indicated at 3l, which will cause a rapid circulation of air currents and 'through which the heated air in the channel 32 may escape. The terminal standards are preferably secured to the outer dome, the inner ends passim"n through apertures in the inner deine but not in contact therewith.

l. have described in detail the constructions illustrated in the accompanying drawings for the purpose of disclosing embodiments of my invention, but it -will he understood that various changes andA modifications may be made Without departing from the spirit thereof.

My invention provides a very eiiicient and exceedingly compact radiator in which the parte are easily assembled and the heater unit and reflector are securely held in position..

An' electric radiator, comprising alreliector, a heating; eleinent connectin standards secured thereto and insulated therefrom, means for detachably securin the heating element to the inner ends o. said standards, means for .securing the terminals or' an.' electric cord conductor to the opposite ends of said standards, and a resilient metal lsupport fastened to said reflector and adapted lto he supported by said cord conductor having an extended heat radiating surface.

An electric radiator, comprising a reflector, heating element, standards extending through apertures in said reflector and having separable members provided with connecting means adapted 4to hold an insulatingl medium adjacent said apertures, and fastening devices carried upon opposite ends of said standards.
